ALBERT B. LIPP, OF SIDNEY, MISSOURI.

DUST-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 770,762, dated September 27, 1904.

Application filed April 20, 1904. Serial No. 204,096, No moeln To all whom it may concern:

Be it known that I, ALBERT B. LTPP, a citi- Zen of the United States, residing at Sidney, inthe county of Putnam and State ofMissouri, have invented a new and useful Dust-EX- tractor, of which the following is a specification.

This invention relates to devices for removing dust from carpets and other Hoor-coverings and from other objects, and has for its object to improve the construction and produce a device of this character inexpensive to manufacture, eflicient in operation, and which may be readily and easily operated and relieved of its accumulation of dust when the operation is completed.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to Without departing from the principle of the invention or sacrificing any of `its advantages, and the right is therefore reserved of making' all the changes and modifications which fall within the scope of the invention and the claims made therefor.

In the drawings thus employed Figure 1 is a sectional elevation. Fig. 2 is a side elevation. Fig. 3 is a transverse section on the line 3 3 of Fig. 1.

rlhe apparatus comprises a cylinder 10, having a piston 11, to which is connected a rod 12, the latter passing through a spider 13, secured to the upper end of the cylinder in any suitable manner, as by a set-screw 14, the upper end of the piston-rod being provided with a handle 30. The piston may be of any preferred form and in this instance is shown as being composed of a disk, which may be of any suitable material, such as leather, and held in position between plates and nuts secured to the lower threaded end of the rod. Attached to the lower end of the cylinder 10 is a casing 15, which is divided into three chambers or compartments consisting of a dust-collecting chamber 16, having a contracted inlet 17, a suction-chamberl 18, communicating with the cylinder, and a dust-rcceiving chamber 19, extending laterally from the chambers 16 and 18 and communicating with the suction-chamber. The casing 15 is coupled to the cylinder by an encircling band 28, the upper portion of the casing being rounded to conform to the cylinder, and the band being held in position by a set-screw 31. Between the chambers 16 and 18 is a partition having an opening 20, and in the wall of the suction-chamber is an opening 21 communicating with the receiving-chamber. Vithin the chamber 18 is disposed a valve 22, hinged at 32 and adapted to close or open either of the openings 2O or 21, as required. Extending from the valve is an arm 23, connected by a link 24 to a rod 25, which works in guides 26 and 27,connected, respectively, to the clamping-band 28 and spider 13 and terminates at its upper end in a handle 29, disposed adjacent to the handle 30 of the rod 12. Under the arrangement shown it will be seen that when the rod 25 is moved in one direction the valve will close the opening 20, and when moved in the opposite direction it will close the opening 21.

The operation of the device is as follows: The valve 22 being moved to position to close the opening 21 the mouth of the dust-collecting chamber is allowed to rest upon the iioor and the device is moved slowly thereover, and during this movement the piston-rod is drawn upward, thereby causing the piston to draw dust into the suction-chamber and cylinder. Just before the piston reaches the limit of its upward stroke the valve is thrown into position to close the opening 20, thereby caging the dust within the suction-chamber and the cylinder. The dust of course will settle upon the valve 22, and to cause the same to be discharged into the receiving-chamber the device is tilted to one side, with the dust-receiv- IOO ing chamber downward, and by gently shaking or tapping the structure the dust will loev discharged 'into the receiving-chamber, after which the valve is again actuated to close the opening' 21. When the operation is completed and it is desired to discharge the receiving-chamber of its contents, the valve is moved to the position to close the opening 20, it being understood that at this stage of the operation the piston is to be at the top of the cylinder. The device is then tilted to bring the receiving-cham ber upward,and by slightly shaking the structure the dust will be fed into the suction-chamber and by inverting the device the dust will be caused to enter the cylinder, where it will lodge upon the piston. i

While the device is still in inverted position the valve is moved to close the opening 2l, and upon the device being brought to its normal or vertical position the dust may be discharged into any suitable receptacle.

The device of the present invention, while exceedingly simple of construction, will be found of the highest eiciency and durability in use and owing to the construction and organization of its parts may be made to do long-continued service without necessitating repairs..

Having thus fully described my invention, what I claim isl. An apparatus of the class described comprising a cylinder, a piston therein, a suctionchamber communicating with the cylinder, a dust-collecting chamber carried by and communicating with the suction-chamber, a dustreceiving chamber projecting laterally from the suction and dust-collecting chambers and communicating with the former, and means to open and close communication between the dust-collecting and suction chambers, `and the suction and dust-receiving chambers.

2. An apparatus of the class described comprising a cylinder, a piston therein and means for operating the same, a suction-chamber carried by the lower end of the cylinder and in communication therewith, a dustcollecting chamber carried-by the suction-chamber, -a dust-receiving chamber projecting laterally Jfrom the suction and dust-collecting chambers, there being openings for establishing communication between the suction and dust-receiving chambers and between the suction and the dust-collecting chambers, a valve arranged in the suction-chamber and adapted to open and close the said openings, and a rod operatively connected with the valve and projecting upward to the top of the cylinder.

3. An apparatus of the class described comprising a cylinder, a piston therein, a dust-collecting chamber having a narrow inlet, a suction-chamber connecting the dust-collecting chamber and cylinder and communicating with both, a receiving chamber communicating with the suction-chamber, and a valve in theY suction-chamber to open or close commu-nication between the dust-collecting and suction chambers and the suction and'dust-receiving chambers.

In testimony that I claim the foregoing as my own I have `hereto affixed my signature in the presence .of two witnesses,

ALBERT B. LIPP.
